SAMUEL A. BULLOCK, OF PLANDOME, NEW YORK, ASSIGNOR 'IO .ALLY COMPANY, INC., OF NEW YORK, N. Y., CORPORATION OF NEW YORK RUST-PREVENTIVE COMPOSITION.

Specification of Letters Iatent. Patented Jan. 24 1922 N6 Drawing. Application filed August 23, 1920, Serial No. 405,390. Renewed December 6, 1921. Serial To all whom it may concern:

Be it known that I, SAMUEL A, BULLOCK,

of Plandome, in the county of Nassau and- State of New York, have invented a certain new and. useful Improvement'in Rust-P e ventive Compositions, of which improvement the following is a specification.

The object of my invention is the: production of a composition for application to finished surfaces of metals, for the protection thereof from corrosion resultant upon .the action of air, water, or brine, which compound shall possess the capabilities of being readily applied to the surfaces to be protected; of delaying drying hard thereon; of adhering thereto without'liability to be rubbed off by rough handling; and of being readily removed by the application of a suitable solvent when desired.

The improvement claimed is hereinafter set forth. y composition consists of a mixture of bituminous paint, made by blending coal tar, pitch, heavy bodied blown petroleum residual pitch, or asphalt with an oleo resinous mineral thinner, with an evaporating oil, as kerosene, and an oil known in the trade as fuel oil,

which mixture forms a resilient covering for finished metal surfaces, which efl'ectually prevents the formation of rust thereon.

In preparing the composition, I prefer to use the ingredients in about the following proportions, viz: bituminous paint, 75 per cent; evaporating oil, preferably kerosene, 10 per cent; and fuel oil, 15 per-eent. The compositlon 1s sufliciently fiuid to be applied to the surfaces to be protected, by a brush or a1r (gun, and after standing for a few hours, har ens so as to become a resilient covering, which will not be accidentally rubbed off by rough handling of the coated articles, but which is sufficiently soluble to be readily removable by slight rubbing with a rag or waste saturated with kerosene.

I claim as my invention and desire to secure by Letters Patent:

1. A composition, suited for application .to finished metal surfaces, for preventing the formation of rust thereon, comprising bituminous palnt, an evaporating oil, and fuel oil.

2. A composition, suited for application to finished metallic surfaces, for preventing the formation of rust thereon, comprising about 75 per cent bituminous paint, 10 per cent kerosene, and 15 per cent fuel oil.
